heres a pic of one of mine thats just starting to flower on 12/12.
it was started outside end of autumn for 2wks so basically on 12/12 from seed and its got pistils showing now at about 3wks old from seed.
ive had it under a 250w HPS for about a week now.
2nd pic is an outdoors one started about 4-5weeks earlier, well into flowering season so basically 12/12 aswell. its not in good soil and not fed too well either though.
